ElderCraft (Sambucus nigra)
ElderCraft is a standardized extract of Sambucus nigra (European elderberry) characterized by high concentrations of quercetin glycosides (293.1 µg/g) and caffeoylquinic acid phenolics. These flavonoid compounds demonstrate free-radical scavenging activity in vitro, though human clinical evidence for antioxidant efficacy remains limited.

Origin & History
ElderCraft is a branded standardized extract derived from the flowers of Sambucus nigra L. (black elder), a deciduous shrub native to Europe, North Africa, and parts of Asia. The flowers are extracted using aqueous methods at 50-90°C with agitation, or ultrasonic-assisted extraction with 70% methanol, yielding a polyphenolic extract rich in flavonoids and phenolic acids.
Historical & Cultural Context
Sambucus nigra flowers have been used in European traditional medicine for their bioactive flavonoids, antioxidants, and phenolics in healing preparations. While historical use spans traditional herbal systems, specific duration and therapeutic indications are not quantified in available sources.
Health Benefits
• Antioxidant support through high phenolic content (based on in vitro DPPH assays only - no human studies available) • Rich source of bioactive flavonoids including quercetin derivatives (293.1 µg/g) - evidence limited to chemical characterization • Contains phenolic acids like caffeoylquinic acid (879.3 µg/g) - no clinical efficacy data • Traditional immune support use in European herbal medicine - historical use only, no clinical validation • Potential free radical scavenging properties - based solely on laboratory antioxidant assays
How It Works
ElderCraft's quercetin derivatives inhibit free-radical chain reactions by donating hydrogen atoms to neutralize reactive oxygen species, as measured by DPPH radical scavenging assays in vitro. Caffeoylquinic acid phenolics may inhibit NF-κB transcription factor activation, potentially modulating pro-inflammatory cytokine expression including TNF-α and IL-6. Quercetin's flavonoid backbone also demonstrates affinity for lipoxygenase enzyme inhibition in cell-based models, which may contribute to its proposed immunomodulatory profile.
Scientific Research
No human clinical trials, randomized controlled trials, or meta-analyses have been conducted specifically on ElderCraft or Sambucus nigra flower extracts. Available research focuses exclusively on chemical characterization and in vitro antioxidant activity measurements, with no PubMed-indexed clinical outcome studies identified.
Clinical Summary
The primary evidence base for ElderCraft's antioxidant properties derives from in vitro DPPH radical scavenging assays and chemical characterization studies quantifying phenolic content, not human randomized controlled trials. No published human clinical trials specifically using the ElderCraft trademarked extract were identifiable at the time of this review. Broader Sambucus nigra research includes small RCTs (n=60 or fewer) examining elderberry preparations for upper respiratory duration, but these used different extract formulations and cannot be directly extrapolated to ElderCraft. The overall evidence strength for this specific ingredient must be rated as preliminary, with phytochemical characterization outpacing clinical validation.
Nutritional Profile
ElderCraft is a standardized extract of Sambucus nigra (European elderberry), typically produced from the berry fruit. Key bioactive compounds and nutritional characteristics include: **Anthocyanins:** Primarily cyanidin-3-glucoside and cyanidin-3-sambubioside, which are the dominant pigment compounds; standardized extracts typically contain 12–17% anthocyanins by weight, though bioavailability is notably low (estimated <1–2% absorption in humans, with rapid metabolism to phenolic acid metabolites such as protocatechuic acid and phloroglucinaldehyde). **Flavonols:** Quercetin-3-rutinoside (rutin) and quercetin-3-glucoside are present; quercetin derivatives measured at approximately 293.1 µg/g in characterized extracts. Quercetin oral bioavailability is estimated at 2–5% in glycoside form, improved modestly by the glucose moiety. **Phenolic acids:** Chlorogenic acid (5-caffeoylquinic acid) is the predominant phenolic acid at approximately 879.3 µg/g; also contains neochlorogenic acid (3-caffeoylquinic acid) and cryptochlorogenic acid (4-caffeoylquinic acid). Chlorogenic acid bioavailability is moderate (~33% absorbed, largely via colonic microbial hydrolysis to caffeic acid). **Other polyphenols:** Minor amounts of kaempferol glycosides, isorhamnetin derivatives, and p-coumaric acid. Total phenolic content typically ranges from 30–50 mg gallic acid equivalents (GAE) per gram of dry extract. **Vitamins (in whole berry, not concentrated extract):** Vitamin C (~18–36 mg per 100 g fresh berries), though levels in processed extracts are significantly reduced due to thermal degradation. Small amounts of vitamin A (as carotenoids, ~30 µg RAE per 100 g fresh fruit), vitamin B6 (~0.23 mg/100 g), and folate (~6 µg/100 g). **Minerals (whole berry basis):** Potassium (~280 mg/100 g), calcium (~38 mg/100 g), phosphorus (~39 mg/100 g), iron (~1.6 mg/100 g), and magnesium (~5 mg/100 g); mineral content in standardized extracts is generally not characterized or standardized. **Macronutrients (whole berry):** Approximately 80% water, 18 g carbohydrates per 100 g (including ~7 g dietary fiber), 0.5 g fat, 0.66 g protein per 100 g fresh berries. Sugars include glucose and fructose. As a concentrated extract product, ElderCraft is consumed in small doses (typically 300–600 mg/day) so macronutrient contribution is negligible. **Lectins and cyanogenic glycosides:** Raw elderberries contain sambunigrin (a cyanogenic glycoside) and Sambucus nigra agglutinin (a ribosome-inactivating lectin); proper thermal processing and extraction in commercial ElderCraft products is intended to reduce these to safe levels, though exact residual concentrations are not always publicly disclosed. **Bioavailability summary:** The dominant bioactives (anthocyanins, flavonol glycosides) have low systemic bioavailability; their metabolites (phenolic acids, glucuronide/sulfate conjugates) may be the primary circulating bioactive forms. Colonic microbiota play a significant role in metabolism of elderberry polyphenols, suggesting interindividual variability in biological response. No standardized human pharmacokinetic data specific to ElderCraft formulation is publicly available as of current literature.
Preparation & Dosage
No clinically studied dosage ranges are available as no human trials have been conducted. Current preparations yield extracts with 86% hydrophilic phenolics or total phenolic content measured against caffeic acid standards, but therapeutic doses remain unestablished. Consult a healthcare provider before starting any new supplement.
Synergy & Pairings
Vitamin C, Zinc, Echinacea purpurea, Vitamin D3, Quercetin
Safety & Interactions
Raw or unripe elderberries contain sambunigrin, a cyanogenic glycoside that can cause nausea and vomiting, though standardized processed extracts like ElderCraft are generally considered safe when properly prepared. ElderCraft may theoretically potentiate immunosuppressant medications (e.g., cyclosporine, tacrolimus) due to proposed immunomodulatory activity, warranting caution in transplant patients. Quercetin-containing supplements can inhibit CYP3A4 and P-glycoprotein drug transporters at high doses, potentially affecting bioavailability of statins, certain antibiotics, and anticoagulants like warfarin. Insufficient safety data exists for use during pregnancy or lactation, and use should be avoided in these populations without physician supervision.
